Sampling SIM: This program allows the
student to explore the nature of sampling distributions of sample means and
sample proportions. The software provides separate windows for building population
distributions, drawing and viewing random samples from the population, exploring
the behavior of sampling distributions of sample means, and exploring the
behavior of confidence intervals. The software is written for the Apple Macintosh
computer and will work on 68040 machines and higher (PowerPC, G3, and G4).
A Windows version is also available that works with Windows 95 and higher.

Standard Distributions: This program allows students
to explore the characteristics of the standard normal distribution and Student's
t-distribution. The software is written for the Apple Macintosh computer and
will work on 68040 machines and higher. We are currently working on a Windows
version of the software.
